DecIP6HLIM Element Documentation

NAME

DecIP6HLIM -- Click element;

SYNOPSIS

DecIP6HLIM()

Ports: 1 input, 1-2 outputs
Processing: agnostic, but output 1 is push
Package: ip6 (core)

DESCRIPTION

Expects IP6 packet as input. If the hlim is <= 1 (i.e. has expired), DecIP6HLIM sends the packet to output 1 (or discards it if there is no output 1). Otherwise it decrements the hlim, and sends the packet to output 0. Ordinarily output 1 is connected to an ICMP6 error packet generator.

EXAMPLES

This is a typical IP6 input processing sequence:

 ... -> CheckIP6Header -> dt::DecIP6HLIM -> ...
 dt[1] -> ICMP6Error(...) -> ...

SEE ALSO

ICMP6Error, CheckIP6Header
